2003 Toyota 4Runner Problems

Car Won't Start Due to Worn/Corroded Solenoid Contacts in Starter

Brake master cylinder may need replacing at 125,000 miles

At 125,000-150,000 miles, the Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes will drag and over heat.

Service AC system at 150,000 miles or every two to three years

Usually by 150,000 miles the AC system will need some attention, especially in climates where it is used often. Our technicians tell us that it is best to service the AC system every 2-3 years. This keeps the moisture in the system at a minimum which extends the life of the components.

Accelerator Pedal May Stick Open

The accelerator pedal can become trapped under an unsecured or incompatible floor mat. This can cause the accelerator pedal to stick in the wide open position, increasing the risk of a crash. At this time, the remedy plan is still under development, but will most likely involve modification or replacement of the accelerator pedal and Toyota all-weather floor mats. No schedule of owner notification is available at this time. The Toyota recall number is 90L; the Lexus number is 90LG.

we like our 2003 4runner but it is not that roomy for a family of 4 the ride is rough like a truck and it is not really a good winter truck
Great truck. it has over 90k miles on it and still drives like new. It has seen everything from beach driving to blizzard conditions and has never failed on me. Still feels solid and seems like it will last forever. I've driven other model SUVs with the same mileage and they feel like they're going to fall apart any minute.
